UNITED STATES PATENT OFFICE.

JUSTUS A. TRAUT, OF NEW BRITAIN, CONNECTICUT.

BUTTON.

SPECIFICATION forming part of Letters Patent No. 437,874, dated October 7, 1890.

Application filed October 22, 1889. Serial No. 327,838. (No model.) i

To aZZ whom it may concern.-

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Buttons, of which the following is a specification.

My invention relates to improvements in buttons of the class in which the cloth is clamped between two parts; and the main objects of my improvements are to more conveniently attach the button without the aid of a driving-tool, and to better hold it in place when attached.

In the accompanying drawings, Figure l is a central sectional view of one part of my button with the other part in side elevation. Fig. 2 is an end view of the screw part of said button; and Fig. 3 is an end view of the outer part, showing the inside end.

4 designates the hollow head of the button; 5, its narrow neck; 6, its base, and 7 the toothed flange. The neck 6 is hollow and screw-threaded, as shown. These parts may be in their general form of any ordinary construction. I form a hollow boss 8, Fig. 1, at the central portion of the hollow head, so as to increase the length of the button in the direction of its axis. The base 6 extends outwardly from the narrow neck at substantially right angles thereto, and the toothed flange 7 stands at right angles to said base and is therefore parallel to the axis of the button. The teeth of the toothed flange are all truncated and blunt, so that while they may embed themselves into the cloth they do not cut or tear the same or break or sever the fibers of the cloth.

The other part of my button consists of a screw 9, having a twisted or corkscrew point 10 in the form of a tapering and spirallycoiled wire and a knurled head 11. The diameter of the head is equal to or a little in hollow head. The combined length of the corkscrew-point and screw under the head should not be greater than the length of the button from the bottom of the toothed flange to the inside of the boss 8 in the button-head. By making the point round in cross-section and on a twist like a corkscrew the taper may be more gradual as it extends over a greater length than could be done if the point were straight. Italso enters the cloth more readily, and when entered draws itself in as the screw is revolved, merely pushing the fibers of the cloth to one side without cutting or breaking them.

Prior patents show buttons having a notched or toothed flange with sharp teeth and a headed or flanged screw provided with slots or nicks for the application of a driver of some kind, and with projecting arms for application of the fingers. Other patents show a corkscrew-point on a plain shank of much smaller diameter than the circle on which the point is curved and pointed screws on one part of the button, said point in one instance being grooved, and the same are hereby disclaimed.

By my improvement the button may be applied without the use of any special tool or tools for puncturing the cloth or for driving the screw. By making the teeth of the flange truncated or blunt instead of bringing them to a point one may fasten or unfasten the button by turning the hollow head 4, while the screw part of the but-ton is stationary, the shape of the teeth permitting the part 4 to revolve, and its teeth ride over the cloth without cutting, breaking, or tearing its fiber. At the same time the teeth will embed themselves in the fiber sufficiently to prevent accidental displacement.

I claim as my invention- The herein-described button, consisting of a headed screw, the button-head 4, narrow neck 5, the base 6, extending outwardly therefrom at right angles to the axis of the button, and the toothed flange 7 at the outer edge of said base, said flange and its teeth being parallel to the axis of the button, substantially as described, and for the purpose specified.
